What Zhang Zhenren has been holding back for a hundred years is not the cultivation of Qi, but the evil fire that wants to burn the world.
After returning from rebirth, he hated the "Grand Master" arch. In his previous life, he followed rules and abided by morality, but he could only watch helplessly as his apprentice was forced to death and Wudang suffered humiliation. In this life, he no longer wants to be a god, he wants to be the biggest "demon" in the martial arts world.
On the surface, he recruited many disciples, spread the branches and leaves, and built Wudang into an unshakable Mount Tai and Beidou; secretly, he used a hundred years of experience and wisdom to weave an invisible network that enveloped the world. All sects that owe blood debts will become trapped beasts in his chess game.
Since the world is a man-eating quagmire, then he, Zhang Sanfeng, must be the evil ghost who drags everyone into the abyss.
These two versions respectively strengthen the sense of resourcefulness of the "operator" and the sense of determination of the "subversive". Which one do you think is more in line with your vision of the protagonist? If necessary, further adjustments can be made.
